Exam 4: The Peripheral Nervous System: Sensory, Autonomic, Somatic

Match the types of autonomic receptors, labelled a. through e., with their characteristic(s). (More than one answer may apply.) -adrenergic receptors found primarily in the heart

Binding of ACh with receptor sites on the motor end plate opens chemical messenger-gated cation channels in the motor end plate, bringing about depolarization of the motor end plate.

Match the divisions, labelled a. through d., with the anatomical and physiological autonomic features. (Options may be used more than once or not at all.) -decrease exocrine activity of the pancreas

Which statement applies to the fovea

Match the receptors, labelled a. through c., to their locations. (Options may be used more than once or not at all.) -taste buds

The terminals of both autonomic nerve fibres and motor neurons end in a single, enlarged knoblike structure that releases neurotransmitter.

Match the type of nociceptor, labelled a. through c., with the properties associated with each type of nociceptor. (Options may be used more than once or not at all.) -transmits its signals via A-delta fibres

Which of these neuromodulators is NOT capable of binding to opiate receptors in the analgesic pathways

The identical nerve pathway conveys information regarding pressure and temperature sensations of the thumb.

Which of these situations can activate the slow pain pathway

Which of the following happens during accommodation for near vision

Sour taste represents a stimuli caused by ________________.

Visual and hearing receptors are irreplaceable, but taste and olfactory receptors are continuously renewed.

Describe the events that occur at a skeletal neuromuscular junction.

Describe how sensory adaptation occurs.

Relaxation of the ciliary muscle changes the cornea into a flattened shape.

Which statement describes the tympanic membrane

A concave lens is used to correct for a myopic eye.

Match the receptors, labelled a. through d., with their function. -generates action potentials in afferent neuron by opening messenger-gated channels

Match the rods and cones, labelled a. through c., with their properties. (Options may be used more than once or not at all.) -contain opsin and retinene
